GROUNDWAVE SUPPLYGroundwave Supply · Pocket Almanac
No grid. No signal. Still answers. 150+ survival manuals, FEMA's hazard guides, all of Wikipedia, and an AI to ask. On the device.
The Pocket Almanac is a phone-sized device that belongs in the 72-hour kit next to the water and the radio. It carries the reference shelf for when things go wrong: FEMA emergency guides, US military survival manuals, a full medical encyclopedia, offline maps, the complete English Wikipedia, and an AI that answers plain-English questions from all of it. No tower, no router, no server.
The kit covers supplies. This covers answers.
A 72-hour kit is food, water, light, a radio, first aid. The item nobody packs is the one you reach for mid-emergency: the instructions. The Pocket Almanac turns on into a chat screen. Type a question, or say it out loud, and it answers from what is physically stored on board, with the source named. It never needs a network because it never phones home for anything. Charge it, ask it things, keep it in the bag.
What's in it when the lights go out
The device is small. The library on it isn't. It ships with the complete English Wikipedia, a dedicated medical encyclopedia, and a shelf of field manuals you'd otherwise track down one at a time from a dozen different sources. Every title is listed by name on the device's own Library screen, so none of this is a marketing tally, it's what's on board.
The military set comes from the Army's own publishing office and includes every era of the Army survival manual, plus the manuals on first aid, water treatment, cold weather, mountaineering, and field hygiene. The FEMA set is their hazard-by-hazard emergency guides and the full "Are You Ready?" preparedness manual. The pre-1928 books cover the skills from before anyone assumed a hardware store was nearby: blacksmithing, canning, well-digging, tanning.
The AI reads the whole shelf with you: ask in plain English, get the answer with the source named, every radio off. It's the librarian, not the doctor.
Connect it to your home Wi-Fi whenever you want, and it pulls down the newest library snapshot and AI model, free, for as long as you own it. Skip that forever if you'd rather; out of the box, offline, it works exactly the same.
Airplane mode on. It still answers.
Airplane mode is the honest stand-in for a dead network: every radio off, no tower, no Wi-Fi, no server on the other end. The demo clip on this page shows the device answering a real question that way, at real speed. An answer takes a few seconds to write itself out, and we left the wait in because that's what using it feels like: a reference tool that thinks for a moment. In a blackout it works exactly the way you see here.
Why this exists
I'm writing this from a base camp in the mountains, two days into a month off-grid. In those two days I've reached for my phone three times to ask something and gotten nothing.
Tracks in the mud near camp, big ones. I wanted to ask what left them. No service. I found out hours later, back where I had signal: black bear. I'd have liked to know that while I was standing next to them.
A lake I hiked to and badly wanted to swim in. I couldn't check whether it was safe and I didn't know the area, so I skipped it. Looked it up that evening: completely fine. Missed swim.
A downhill bend on a road I wanted to skate. I couldn't pull up a map to see how far the hill ran, and I wasn't walking back up it. Never rode it.
Nothing dangerous, and that's the point. Being out here is a hundred small questions, and every answer lives on a phone that goes dumb at the trailhead. So we made one that doesn't.

First batch, numbered and dated
Gear you might stake real decisions on should tell you exactly what it is. Every unit in the first batch gets loaded from the same dated build, then tested and sealed by hand before it ships. Your batch number and date are printed on the device. Each batch also gets a short published note: the AI model version, the Wikipedia snapshot date, and the things it doesn't do well, listed plainly. A $2 deposit reserves a unit in this batch and locks your price at $249 instead of the $299 launch price.
The first batch is one bounded run. When it's fully reserved, the next batch ships later, with a newer build and its own notes.
Verify it before you rely on it
- Every manual and reference onboard listed by name on the device's own Library screen
- Fully offline: the manuals, maps, Wikipedia, and the AI live on the device, not in a cloud
- The demo runs in airplane mode, at real answer speed
- Every unit hand-loaded, tested, and sealed before it ships
- Free library and AI updates over Wi-Fi, for as long as you own it, no subscription
- Phone model, memory, and AI version named on the batch's spec sheet
Launch price will be $299. Reserving now locks yours at $249. The $2 is a reservation, not an order, so we don't collect shipping details yet. It's fully refundable: it counts toward your $249 if you keep the reservation, and comes straight back if you cancel.
